SEALABLE PAIL.

Application filed December 7, 1921.

This invention relates to containers and particularly pertains to a sealable pail or bucket.

It is the principal object of the present invention to provide a container especially adapted for use by candy manufacturers and the like and within which they may seal and ship their goods, the head being held in position so that access cannot be had to the interior of the pail, the structure further lending itself to use after the contents of the pail have been removed. As, for example, the dealer may sell the contents of the pail and then market the pail as a first-class article.

The present invention contemplates the formation of a metal container substantially cylindrical in shape and having a croze formed around the mouth thereof. Adjacent this croze a chine is formed, these members receiving a head which is collapsible and may be readily removed from the mouth of the bucket, or may be securely sealed in position.

The invention is illustrated by way of example in the accompanying drawings, in which:

Fig. 1 is a view in plan showing the complete structure with which the present invention is concerned.

Fig. 2 is a view in side elevation with parts broken away showing the bucket and particularly disclosing the structure of the cover.

Fig. 3 is a fragmentary view in section and elevation taken through the cover at right angles to the view shown in Fig. 2 and further showing the sectional formation of the cover.

Referring more particularly to the drawings, 10 indicates a pail or other like container. Here shown this pail is formed with a bail 11 by which it may be carried. The pail may be of any desired construction, although it is preferable that it be made of light, cheap metal. A croze portion 12 is rolled aroundthe mouth of the pail and a chine forms the finish of the marginal edge of the pail, as indicated at 12. A suitable reinforcing chine ring 14 is rolled into the structure of the chine for a purpose which will readily be understood. The mom as here shown is substantially semi-circular in sectional formation although it may be otherwise formed and extends completely 'serted in the croze.

18 are identical and, as shown in Fig. 1, I

are substantially semi-circular. The member 17 is formed of two parts A and B which are disposed in longitudinal alignment and fit between the sections 16 and 18. The adjacent edges of the section 17 and the opposite side sections 16 and 18 are bevelled relative to each other, as shown in Fig. 3. This will insure that when the middle section 17 is placedin after the side sections have been positioned, it will be impossible to remove the side sections without first having to remove the middle section. The meeting edges of the two portions A and B of the middle section are also beveled, as shown in Fig. 2. The portion A of the middle section 17 is provided with a locking bar 19 and this bar is longitudinal in section and overlaps the section B. The looking bar is formed at its ends with a slot 20 which receives a staple 21. This staple extends upwardly through the slot and is provided to receive a lock pin 22. The lock pin is perforated, as shown at 23, and thus accommodates the wire 24 of a lock and seal 25 It will be evident that when the wire is passed through the staple and the pin, the bucket will be locked so that the cover cannot be removed, and, due to the bevelled edges of the cover section, it will be impossible to remove any one of the sections without first breaking the seal and removing the central panel 17. In order to permit the bucket to readily stack during shipping blocks 26 are fastened to the upper faces of the cover panels 16 and 18. These blocks have their faces on a level with the lock bar 19 and thus will present a level supporting surface.

In the operation of the present invention the bucket is formed as shown in the drawings with the croze and chine portions. The bucket covers may then be applied, either before if the bucket is empty, or after the bucket has been filled. The cover is applied by first positioning the panels 16 and 18 within the croze and thereafter disposing the panel section 17 in position. The outer ends of the portions A and B are first in- This will cause the central portion of the structure to extend ups23 eonora wardly in V-shaped formation. The locl; bar 19 is then forced downwardly and the portions and B of the middle panel brought into alignment, as shown in 2. The staple :21 may then he used to loclthe bar in position when the pin has heen inserted through the staple. The wire may then he passed through the opening in the pin and through the staple, after which is sealed by the aling member 25.

it will thus he seen that the pail here disclosed may he used as a container for purpose and may be sealed and locked so that it cannot he opened by unanthoifzed persons. At he same the contents of the pail may b8 removed and the container thereafter sold or retried.
